The surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm

<h3>How to find the surface area of a figure?</h3>

The surface area of a square pyramid is equal to the sum of the ara of the base square and the four triangle.

<h3>Find the area of the square base</h3>

Area of the base = 10cm * 10cm

Base area = 100 sq,cm

Find the area of a triangle

Area of triangle = 0.5 * 10 * 14

Area of a triangle = 70 square cm

Area of 4 triangles = 4(70) = 280 sq.cm

<h3>Determine the surface area</h3>

SA = 100 + 280

SA = 380 sq. cm

Hence the surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm

Find the product 3/4x2/5 and express the answer in simplest form

yanalaym [24]

We have the expression:

$\frac{3}{4}*\frac{2}{5}$

To multiply fractions, we are going to multiply the top (straight across the top of the fraction bars) and multiply the bottom (straight across underneath the fraction bars). So then we have:

$\frac{3}{4}*\frac{2}{5}=\frac{6}{20}$

But since both the numerator and denominator are divisible by 2, we can reduce the fraction to:

$\frac{6}{20}=\frac{3}{10}$

So then the most simplified answer is $\frac{3}{10}$ .

sorry im duxmxb what does 'congruent' mean and gimme an example maybe? ik im just young and i dun wanna bother anyone .-.

Hiiiii ^-^ I can help you XD

Congruent
The same shape and size.

Two shapes are congruent when you can Turn, Flip and/or Slide one so it fits exactly on the other.

In this example the shapes are congruent (you only need to flip one over and move it a little).

Angles are congruent when they are the same size (in degrees or radians).
Sides are congruent when they are the same length.

How do I solve this question?

g100num [7]

Answer:

$-7 \frac{1}{2}$

Step-by-step explanation:

$\frac{6 {x}^{ - 1} {y}^{ \frac{7}{2} } }{ \sqrt{16 {x}^{2} } {y}^{2} } \\ \\ = \frac{6 {x}^{ - 1} {y}^{ \frac{7}{2} } }{ \sqrt{(4 {x} {y})^{2} }}\\ \\ = \frac{6 {x}^{ - 1} {y}^{ \frac{7}{2} } }{ {4 {x} {y}}}\\ \\ = \frac{6}{4} {x }^{ - 1 - 1} {y}^{ \frac{7}{2} - 1 } \\ \\ = \frac{3}{2} {x }^{ - 2} {y}^{ \frac{5}{2} } \\ \\ equating \: it \: with \: \\ a {x}^{b} {y}^{c} \\ \\ \implies \\ a = \frac{3}{2} \\ \\ b = - 2 \\ \\ c = \frac{5}{2} \\ \\ abc = \frac{3}{2} \times ( - 2) \times \frac{5}{2} \\ \\ = - \frac{15}{2} \\ \\ =- 7 \frac{1}{2} \\$
